RELATED APPLICATIONS
[0001] This application is a continuation and claims priority
benefit of U.S. patent application Ser. No. 10/462,897, filed Jun.
13, 2003, which is a divisional and claims priority benefit of U.S.
Pat. No. 6,604,443 filed Jul. 23, 2001. The disclosures of U.S.
patent application Ser. No. 10/462,897 and U.S. Pat. No. 6,604,443
are hereby incorporated by reference.
BACKGROUND
[0002] 1. Field of the Disclosure
[0003] The present invention relates generally to the field of
window covering sizing machines and more particularly to a blind
and shade cutting center.
[0004] 2. Description of Related Technology
[0005] Mass retail merchandisers sell a large number of window
coverings directly to consumers. Standard sized window coverings
are sized to a consumer's specifications while the consumer waits.
The apparatus employed to size the various window coverings must be
both easy to use by an employee of a retail outlet and should not
require an extensive training period.
[0006] Additionally, the floor space that the cutting apparatus
requires should fit within the existing structure and layout of the
retail outlet. Further, the cutting apparatus ideally should size a
number of different types of window coverings, such as metal or
vinyl mini-blinds, vertical blinds, pleated shades, and cellular
shades.
[0007] Many attempts have been made to integrate various window
covering cutting mechanisms into a single multi-station system. One
example of a multi-station system is disclosed in U.S. Pat. No.
5,456,149 to Elsenheimer et al. entitled "Sizing System for Window
Coverings" issued Oct. 10, 1995. The '149 Patent discloses a
station having a flip-top surface including a pleated shade sizing
station on one side and a mini-blind sizing station on the other.
This system minimizes the space required by the merchandiser to cut
various window covering products. This allows the retail outlet to
include other stock and products in space otherwise occupied by
various window covering sizing equipment.
[0008] Recently, more retail merchandisers utilize 8-foot bay
spacing to display and sell products. Accordingly, a shade and
blind cutting center that can be located within the 8-foot bay
environment is needed.
[0009] The sale of vertical blind products has also increased
through mass merchandiser retail outlets, requiring the ability to
size not only the width of the vertical blind head rail but also
the length of the vertical blind slats. However, if a cutting
apparatus is to be located within an 8-foot bay environment, any
vertical blind slat extending greater than 8 feet would not be able
to be sized with an apparatus located within the 8-foot bay.
Accordingly, there is a need for a vertical blind cutting apparatus
that would fit within the 8-foot bay environment as well as be able
to size vertical blind slat product having a length greater than 8
feet.

DETAILED DESCRIPTION
[0041] Referring now to the drawings, an apparatus for sizing both
blinds and shades for window coverings is generally illustrated in
FIG. 1. The blind and shade cutting center 10 is slidably movable
on rails 12 in and out of a bay 14. The cutting center 10 includes
a first cutting station 16 for sizing mini-blinds, pleated shades,
and cellular shades. The cutting center further includes a second
cutting station 18 for sizing wooden blinds and vertical blinds.
The first and second cutting stations 16, 18 are supported by and
located on opposing ends of a housing 20. A controller mechanism 22
allows an operator to gain access and to control the first and
second cutting stations 16, 18. Further, cutting center 10 includes
a center locating and measuring system 24 to position the blinds
and shades to be sized.
[0042] Referring to FIGS. 2 and 17 the housing 20 of the cutting
center 10 includes a bottom 26, a front wall 28, a first and second
side wall 30, 32, a rear wall 34, and a top working surface 36. For
purposes of this application the cross housing direction is defined
as the direction that is perpendicular to the front wall 28 and
rear wall 34. Similarly, the longitudinal direction will be defined
as the direction that is perpendicular to the first and second side
walls 30, 32. The right side of the housing 20 will be defined from
the perspective of an operator as they face the bay 14.
Accordingly, the first side wall 30 is on the right side of the
housing, while the second side wall 32 is on the left side of the
housing. The longitudinal axis of the housing will be defined as an
axis extending centrally on the top working surface 36 and
perpendicular to the first and second side walls 30, 32. The cross
center axis will be defined as an axis extending centrally on the
top working surface 36 and parallel with the cross housing
direction. The cross center axis is perpendicular to the
longitudinal axis.
[0043] Housing 20 may be moved from a stored position (as
illustrated in FIG. 1) in which the housing 20 is located within
the bay 14 to an operating position (as illustrated in FIG. 2) in
which the housing 20 is located substantially outside of the bay
14. The stored position permits the housing to be completely out of
the aisle of a retail or mass merchandising outlet. In the
operating position, the housing is accessible for an operator to
size a blind or shade product as will be described below. While it
is possible to size a blind or shade product while the housing is
in the stored position, the length of the product to be sized may
be limited by the size of the bay.
[0044] The bay 14 typically includes a front surface 28 and a first
and second side support 40, 42. The supports 40, 42 may be in the
form of a wall or may be in the form of a frame. When the housing
20 is in the stored position, the front wall 28 may be flush with
the front surface 38 of the bay or may be located a distance within
the bay from the aisle to ensure that no part of the cutting center
10 protrudes into the aisle. Further, if the cutting center 10 is
completely located within the bay 14, the possibility of being
damaged by a forklift or customer carts is minimized.
[0045] Housing 20 may include a handle or handles (not depicted) to
facilitate sliding the cutting center 10 in and out of the bay 14
on the rails 12. All of the equipment employed in center 10 is
attached to the housing 20. The only portion of the center 10 that
extends outward from the housing 20 is a vacuum bag 44 of a vacuum
46 (See FIG. 3). The depth of the housing 20 as measured in the
cross housing direction is less than the depth of the bay 14. This
permits the vacuum bag 44 to be situated behind the housing 20 when
the center 10 is in the stored position. Of course the vacuum bag
44 could also be stored inside of the housing 20 and accessed
through the rear wall 34 by an access means such as a door.
[0046] As will be described below, the preferred embodiment
includes a center locating and measuring system as well as an end
locating and measuring system. Both systems allow the operator to
size a blind or shade by referring to only the customer's
specification of the final size and length of the blind. In
contrast, other sizing methods required the operator to calculate
the amount of material to be removed from each side of the blind
and to locate the blind relative to the sizing station accordingly.
This may lead to errors in the final product, resulting in both
scrap material as well as a delay in the time it takes to deliver a
final sized product to the consumer.
[0047] The center locating system positively locates the center of
the blind to be sized, while the end locating system locates the
shade relative to one end of the shade. Where the lift cords are
visible to the consumer such as in a Venetian blind or a pleated
shade it is important that the lift cords remain symmetrical about
the center of the blind. The center locating system employs a half
scale that permits an employee to size the blind by referring to
only the customer's final width of the blind. In contrast, the end
locating system may be used for cellular shades where the lift
cords are hidden from view and it does not matter that the lift
cords are not symmetric about the center of the shade. Similarly,
the end locating system may be used for a vertical blind head rail
and vanes where the products may be sized from a single end.
[0048] Referring to FIGS. 4 and 20, the pin locator 48, the center
clip locator 50, and the end locator 52 are illustrated. Each
locator 48, 50, 52 is attached to a respective carriage 54 having a
plurality of rollers 56 that are slidably received in a rail 58.
The rail 58 extends proximate the front wall 28 of the housing 20
and parallel to the longitudinal axis of the housing 20. The rail
58 and carriage 54 device is available commercially and marketed
under the trade mark Redi Rail.TM.. The pin locator 48 and the
center clip locator 50 illustrated in FIG. 20 are center locating
devices that positively locate the center of the blind or shade to
be sized. The end locator 52 is a locating device that is used to
both square the blind or shade and to locate certain blind and
shade products relative to one end of the blind.
[0049] The pin locator 48 and the center clip locator 50 both
permit a blind to be sized from its center by engaging a center
portion of the blind. The pin locator 48 includes an extension
member 60 attached to the carriage. A pointer 68 is attached to the
carriage 54 and indicates the position of the pin locator 48
relative to the first or second cutting stations 16, 18 by use of a
scale as discussed below. The extension 60 extends in the cross
housing direction from the carriage 54 toward the rear of the top
working surface 36. A first pin 62 extends from the carriage 54
parallel with the top working surface 36 of the housing 20 and
towards the rear wall 34. The first pin 62 is located a
predetermined distance above the top working surface 36. A second
pin 64 may extend from the rear portion 66 of the extension 60
toward the front wall 28 a predetermined distance above the top
working surface 36.
[0050] Pins 62 and 64 each have a cross section that corresponds to
the cross section of an aperture in the bottom rail of the shade or
blind. In the example illustrated in FIG. 6, the pin 62 has a cross
shaped cross section. However, any other shape may be employed as
well, for example a round cross section may be used. Pin locator 48
includes a pointer 68 that identifies the location of the pins 62,
64 relative to the first scale 70.
[0051] The center clip locator 50 is illustrated in FIGS. 4 and 20.
The center clip locator 50 includes an extension 72 attached to the
carriage 54 for slidable movement in the rail 58. A pointer 74 is
attached to the center clip locator 50 that identifies the position
of the locator relative to a second scale 76. The extension 72 of
the center clip locator 50 includes a slot 78 having a width
configured to receive and positively locate a center clip 80
attached to the center portion of the blind head rail or bottom
rail (See FIG. 22.).
[0052] Referring to FIGS. 22 and 23, the center clip 80 is
positively secured to a head rail 82 or bottom rail by positive
location of a protrusion 84 of the center clip with an aperture 86
or other locating device in the center of head rail 82.
Alternatively, the center clip 80 could include an aperture that is
positioned relative to a detent or tab located on the head rail.
Further, any other mechanical means of locating the center clip 80
onto the head rail may be employed. In the preferred embodiment the
center clip 80 is made of a resilient material such that the center
clip 80 may simply be located in the center of the blind head rail
prior to sizing and maintained in place by the spring force of the
center clip 80.
[0053] As illustrated in FIG. 4, the pin locator 48 is positioned
on the right side of the cutting center 10 and the center clip
locator 50 is positioned on the left side of the cutting center 10.
However, this orientation is for illustration purposes only. It is
possible that cutting center 10 includes two pin locators 48 on
both the right and left sides of the cutting center or two center
clip locators 50 on both the right and left sides of the cutting
center 10. Any combination of locators 48, 50 may be employed
depending on the type of locating system that is used to locate the
actual products to be sized.
[0054] The pin locator 48 as illustrated in FIG. 4 is slidably
positioned relative to a cutting plane 88 (See FIGS. 10 and 11) of
the first cutting station 16 by the first scale 70. The first scale
70 is located on the right side of a raised portion 90 proximate
the rail 58 (FIG. 20). Similarly, the center clip locator 50 is
slidably positioned relative to the cutting plane 92 (See FIG. 15)
of the second cutting station 18 by the second scale 76.
[0055] The first and second scales 70, 76 each include half scale
indicia and extend proximate the front edge of the top working
surface and parallel to the longitudinal axis. The first and second
scales 70, 76 include half scale indicia where each unit of
measurement is identified as twice its actual distance from the
cutting planes of the first and second cutting stations
respectively. For example, a distance of fifteen inches (15'') from
the cutting plane 88 of the first cutting station 16 is identified
as thirty inches (30'') on the half scale indicia.
[0056] The half scale indicia allows an employee or operator to
size a window blind by only knowing the final desired width of the
window blind. The width of the window blind is defined as the
horizontal distance between the two sides of the window blind when
the window blind is installed relative to the window or opening to
be covered. The height of the window blind is the vertical distance
that the window blind or shade covers. The term "length" as it is
used in conjunction with the Venetian window blind head rail, slats
or bottom rail will correspond to the width of the window
blind.
[0057] Referring to FIGS. 4 and 20, end locator 52 includes an
extension 94 attached to carriage 54 for translation along rail 58.
Extension 94 extends from the carriage 54 in the cross housing
direction and includes a first side 96 and a second side 98
parallel to the first side 96. The first side 96 faces the first
cutting station 16 while the second side 98 faces the second
cutting station 18. As will be described below the first and second
sides 96, 98 of the extension 94 extend a sufficient distance from
the top support surface 36 to engage the ends of the blind or shade
to be sized to help align the head rail, bottom rail and window
covering material for sizing. Further, the first side 96 is also
used to locate the cellular shade as will be described below. End
locator 52 further includes a set block 100 extending from the
first side 96 a set distance toward the first cutting station 16.
The end locator further includes a cut out region or a depression
102 in the top portion 94 of the extension 94 that permits a
portion of the cellular window covering material of the cellular
blind to extend through the extension 94 when the head rail and
bottom rail are being sized. The end locator is positioned between
the right and left locators, which as illustrated in FIG. 4 is the
pin locator and center clip locator respectively. Of course, as
noted above, the right and left locators may both be pin locators
or center lip locators.
[0058] Referring to FIGS. 7-10, first cutting station 16 will be
described in further detail. First cutting station 16 includes a
stationary die 104 and a moveable die 106 slidably coupled to the
stationary die 104. A guiding die member 108 is secured to a first
face 110 of stationary die 104 to provide a plurality of beveled or
flared surfaces 112 for guiding the various bottom rails, slats and
head rails of the blinds and shades to be sized into openings in
the stationary and movable dies 104, 106.
[0059] Referring to FIG. 8, the stationary die 104 includes three
regions for cutting three different types of window covering
products. The first region 114 is configured for sizing a
mini-blind product having metal or aluminum slats and a metal head
rail and bottom rail. This mini-blind product will be referred to
as the metal mini-blind product. First region 114 of the stationary
die 104 includes a first channel 116 for receiving a bottom rail of
a mini-blind product, and an opening 118 for receiving a plurality
of metal or aluminum slats from the metal mini-blind product.
Further, first region 114 of stationary die 104 also includes a
second channel 120 for receiving the head rail of the metal
mini-blind product.
[0060] Additionally, stationary die 104 includes a second region
122 for sizing a mini-blind having a plurality of vinyl slats. This
mini-blind configuration will be referred to as a vinyl mini-blind
product. This second region includes a channel 124 for receiving
the bottom rail of a vinyl mini-blind product having vinyl slats
and a second opening 126 for receiving the vinyl slats, and finally
a third channel 128 for receiving the head rail of the vinyl
mini-blind product.
[0061] The third region 130 of stationary die 104 is for sizing a
pleated or cellular shade and includes a first pair of channels
132, 134 for receiving the ends of a head rail and bottom rail from
a pleated or cellular shade. Similarly, third region 130 may
include a second pair of channels 136, 138 for receiving the second
ends of the head rail and bottom rail from a pleated or cellular
shade, when the head rail and bottom rail are not symmetric.
However, in the preferred embodiment, the head rail and bottom rail
are symmetric and therefore only a single pair of channels is
required. Accordingly, the second pair of channels 136, 138 is
shown in phantom lines. The third region 130 also includes an
opening 140 for receiving the pleated or cellular material to be
sized.
[0062] Referring to FIG. 9, the movable die 106 similarly has three
regions that correspond with the respective three regions of the
stationary die 104. The first region 142 of the movable die 106
includes a first die opening 144 to receive both the portion of the
bottom rail and metal slats of the metal mini-blind to be sized. A
first blade 146 is attached to the movable die 106 and separates
the first die opening 144 from a second die opening 148 that
receives the portion of the head rail to be sized. The first blade
146 is fastened to the movable die and includes a cutting surface
150 that is proximate the stationary die 104. First blade 146 cuts
both the metal slats and the bottom rail. The geometry of the first
blade 146 permits the metal slats and bottom rail to be sized with
the same blade without the blade chipping when it cuts the bottom
rail member. First blade 146 has an arcuate surface that
corresponds to an arcuate portion on the outer surface of the
stationary die 104. However, other known cutting shapes may also be
employed.
[0063] The second region 152 of the movable die 106 is located
below the first region 142. The second region 152 includes a first
opening 154 to receive both the portion of the bottom rail and
vinyl slats of a vinyl mini-blind to be sized. A second blade 156
is attached to the movable die 106 and separates the first opening
154 from a second opening 158 that receives the portion of the
vinyl mini-blind head rail to be sized. The second blade 156 is
fastened to the movable die 106 and includes a sharpened edge 160
that is proximate the stationary die 104.
[0064] The third region 162 of the movable die 106 is situated in
line with the first region of the movable die such that it
corresponds to the third region 130 of the stationary die 104. The
third region 162 includes a first opening 164 and a second opening
166. A shearing portion 168 is located proximate the first opening
164 and a shearing portion 170 is located proximate the second
opening 166. However, a single opening and shearing portion may
also be used.
[0065] Finally, the third region 162 of the movable die includes a
third opening 172 for receiving the cellular or pleated shade
material to be sized. A blade 174 is attached to the movable die
106 and has a blade edge 176 to cut the cellular and pleated
material as the movable die 106 is moved from a retracted position
illustrated in FIG. 8 to the fully extended position illustrated in
FIG. 9.
[0066] As illustrated in FIGS. 17, 18a, and 18b the stationary and
movable dies 104, 106 are attached to a frame 178 that is movable
from a first position in which the first regions 114, 142 and third
regions 130, 162 of the stationary and movable dies 104, 106 are
proximate the top working surface 36 of housing 20, to a second
position in which the second regions 122, 152 are proximate the top
working surface 36. Further the frame 178 may be moved to a third
position in which the entire first cutting station 16 is lowered to
a position below the top working surface 36 to facilitate the
sizing of vertical blind slats having a length greater than the
width of the housing 20.
[0067] When the entire first cutting station 16 is lowered to a
position below the top working surface 36, an extension scale 180
may be attached to the housing (See FIG. 27). A vertical peg 182
fastens the extension to the housing 20 so that the extension scale
180 remains in a plane parallel with the top working surface 36.
This feature allows a simple disassembly upon raising the first
cutting station 16 and also allows the extension scale 180 to slip
out of its position on the housing if the first cutting station 16
is raised without first removing the extension scale 180. Further,
if the housing is moved back into the bay before removing the
extension scale 180, the scale will simply pivot about the peg 182
to prevent damage to the extension scale 180 or to the housing.
[0068] In the preferred embodiment, the frame is moved between the
first, second and third positions with a hydraulic piston 184 that
is controlled by the controller 22. The hydraulic piston 184 is
shown in FIGS. 17, 18a and 18b.
[0069] In an alternative manual embodiment illustrated in FIG. 19 a
pair of spring biased release mechanisms 186 is located on either
side of the frame 178 to releasably secure the frame in the first,
second or third positions. Each release mechanism 186 includes a
spring biased button 188, each having a spring member 190 biasing a
pin 192 into engagement with one of three pairs of support members
194 attached to housing 20. By manually pulling the engaged pair of
buttons 188 in an outward direction, the pins 192 are released from
the support member 194 and the frame 178 may be moved upward or
downward to another one of the pair of support members. In this
manner, the first cutting station 16 may be moved manually between
the first, second and third positions.
[0070] The method for sizing a metal mini-blind product utilizing
the cutting center 10 will now be described in detail. As discussed
above, cutting center 10 can cut more than one type of mini-blind
or shade product. The first cutting station 16 includes two
different regions for cutting two different types of mini-blind
products. The mini-blind products could have different geometry
necessitating different die openings, and/or different shearing
configurations, and/or different blade combinations. In the example
illustrated in the figures the first cutting station 16 permits the
sizing of two different mini-blind products formed of different
material and having a different geometry. In the preferred
embodiment, the first regions 114, 142 of the stationary and
movable dies 104, 106 of the first cutting station 16 are
configured to size a metal mini-blind product having a metal bottom
rail, a metal head rail and aluminum slats. The second regions 122,
152 are configured to size a vinyl mini-blind product having vinyl
slats.
[0071] A customer will measure the width of the window or windows
to be covered and bring this dimension to a retail outlet to
purchase a mini-blind product. If the mini-blind product in stock
does not match the dimensions required by the customer, an
employee/operator will size a stock size mini-blind product to the
customer's specified dimension. This system only requires that the
operator select the stock mini-blind product having a width greater
than that required by the customer. The operator, as will be
described herein, does not need to calculate the difference between
the stock product and customer's dimensions, nor does the operator
need to divide the difference between the stock mini-blind product
and the customer's specifications. The operator will cut a portion
of the head rail, bottom rail and window covering material from
each end of the stock mini-blind product, without the need to know
any value but the customer's desired end width of the mini-blind.
By removing material from both ends of the mini-blind product as
described below, each pair of lift cords will remain an equal
distance from each respective end of the mini-blind.
[0072] Once the operator has identified and selected the stock
mini-blind product closest to, yet wider than the customer's
specification, the cutting center 10 is pulled from the stored
position in bay 14 as illustrated in FIG. 1 to the extended
position as illustrated in FIG. 2. The operator gains access to the
center controls by entering a password into the center access panel
196 of the control mechanism 22. The control mechanism 22 may be
connected to a computer that identifies the operator seeking access
to the cutting center 10. The computer may also store the
information entered by the operator including the time of entry.
The system may further be programmed to allow the operator to enter
information relative to the stock blind being sized as a way of
monitoring inventory. Additionally, the time required to size the
mini-blind may be recorded. The access panel 196 has the added
benefit of prohibiting unauthorized personnel from accessing the
cutting center 10.
[0073] After the cutting center 10 has been activated by means of
the access panel 196, the operator loads the stock mini-blind
product onto the top working surface 36. As discussed above, both
the pin locator and central clip locator for centrally locating the
stock mini-blind to be sized may be utilized. For illustration
purposes only, the pin locator will be described for locating the
mini-blind product relative to the first cutting station 16 and the
center clip locator will be described for locating the wooden
mini-blind product relative to the second cutting station 18.
However, the center clip locator could be used to locate the
mini-blind product relative to the first cutting station as
well.
[0074] When using the pin locator, the bottom rail of each stock
mini-blind product includes a centrally located aperture or opening
through the bottom most portion of the bottom rail. The aperture
could also be a slot extending perpendicular to the longitudinal
axis of the bottom rail, or an indentation or depression or
connector or any other means for centrally locating the mini-blind
product. The aperture is centrally located in the bottom rail,
however, the aperture or locating means could also be located in
the head rail. The operator locates the aperture onto pin 62 of the
pin locator 48. The portions of the first end of the head rail,
bottom rail and slats that are to be cut off are slid through the
first regions 114, 142 of the stationary and movable dies 104, 106.
The bottom rail is located in channel 116 of the stationary die 104
and opening 144 of the movable die 106. Similarly, the slats are
located in opening 118 of the stationary die 104 and opening 144 of
the movable die 106. Finally, the head rail is located in channel
120 of the stationary die 104 and opening 164 of the movable die
106.
[0075] The stock mini-blind product is positioned relative to the
cutting plane 88 of the first cutting center 16 by lining up
pointer 68 of the pin locator 48 with the customer's specification
on the half scale indicia on first scale 70. The half scale indicia
is dimensioned relative to the cutting plane 88 of the first
cutting station 16 which is generally defined by the outer surface
of the stationary die 104 that determines the location of the sized
end of the head rail, bottom rail and slats after the movable die
106 is activated and shears and/or cuts the head rail, bottom rail
and slats. The half scale units are one half of the actual distance
from the cutting plane. For example thirty (30) inches on the half
scale is only one half of thirty (30) or actually only fifteen (15)
inches from the cutting plane. Once the movable die 106 is
activated the newly cut ends of head rail, bottom rail and slats
will be 15 inches from the center aperture.
[0076] To activate the movable die 106 in the first cutting station
16, the operator turns on the first cutting station 16 with an
on/off switch located on the controller 22. By simultaneously
depressing the two activation buttons, the movable die 106 is moved
from the rest position to the extended position by a plunger 198
that is driven by a pneumatic or hydraulic cylinder 200. The first
blade 146 shears the slats and subsequently the bottom rail, while
the shear portion of opening 148 shears the head rail. If the
operator releases the activation buttons during the cutting
process, the movable die 106 will stop. This feature ensures that
the operator's hands are safely away from the movable die 106
during the activation sequence. Once the movable die 106 is fully
extended and the first end of the head rail, bottom rail and slats
are sized, the movable die 106 retracts to the rest position.
[0077] After the first side of the mini-blind product is sized, the
operator removes the mini-blind product from pin 62 and rotates it
such that the sized end of the mini-blind product is away from the
first cutting station 16. The center aperture on the bottom rail of
the mini-blind product is once again located on pin 62. Once the
mini-blind has been located, the movable die 106 is activated and
the second side of the head rail, bottom rail and slats are sized.
In this example the desired width of the mini-blind product was
thirty (30) inches. Since each side of the blind was sized relative
to the central locating hole in the bottom rail, the cut ends of
the mini-blind product are fifteen (15) inches from the center for
a total mini-blind width of thirty (30) inches. In this manner the
lift cords are equal distance from the center of the mini-blind
product and equal distance to their respective ends of the sized
mini-blind product.
[0078] The sizing of the metal mini-blind occurs while the first
cutting station 16 is in the first position relative to housing 20
as described above. A vinyl mini-blind is sized in a second
position of the cutting station. To move the first cutting station
16 to the second position utilizing the hydraulic piston, the
operator utilizes the controller 22 to move the first cutting
station 16 to the second position. In the alternative embodiment,
the manual release mechanism 185 may be used to move the frame. The
buttons 188 of the release mechanism are pulled outward releasing
the pins 192 from the support members 194 thereby permitting the
operator to move the first cutting station 16 upward until the
buttons are aligned with and engaged with a second pair of support
members 194. The steps for sizing the vinyl mini-blind in the first
cutting station are the same as the steps for sizing the metal
mini-blind as described above. However, the vinyl mini-blind is
sized in the second regions 122, 152 of the stationary and movable
dies 104, 106.
[0079] The process of sizing a pleated or cellular shade will now
be described. The pleated material is sized independently of the
bottom rail and head rail. The shearing portions 168, 170 of the
third portion 162 of movable die 106 that are used to size the
bottom rail and head rail of a pleated shade are not sharp enough
to cleanly cut the material. The pleated material is sized in a
separate step from the sizing of the head rail and bottom rail
utilizing a sharp blade 174. In a pleated blind the lift cords are
visible and therefore it is desirable to have the pair of lift
cords be symmetrical with respect to the center of the pleated
blind. Accordingly, the pleated blind may be sized in four distinct
steps. First one end of the head rail and bottom rail are sized to
the final width of the pleated shade. Second, one end of the
pleated material is sized. Third, the other end of the head rail
and bottom rail is sized. Fourth, the other end of the pleated
material is sized.
[0080] The steps for removing the cutting center 10 from the bay
14, and accessing the cutting center 10 is the same as that
described above for sizing the mini-blind products. Additionally,
the first cutting station 16 is moved to the first position to size
the pleated shade product. This is the same position as when the
metal mini-blind product is being sized.
[0081] As with the mini-blind products discussed above, the bottom
rail of the pleated shade includes an aperture which is located on
pin 64 of pin locator 48. In contrast to the front pin 62 utilized
to locate the mini-blind products, the rear pin 64 is utilized to
locate the pleated or cellular shade. By using the half scale
indicia of the first scale 70, the pin locator 48 is aligned with
the finished dimension of the customer's specification.
[0082] The first end of the head rail and bottom rail are slid into
channels 132, 134 respectively and openings 164, 166 of the movable
die 106. The pleated material however, is not slid into any opening
at this time, but rather the pleated material is slid relative to
the bottom rail and head rail, so that one end of the pleated
material extends past the second end of the head rail and bottom
rail. The first cutting station 16 is activated as discussed above
with respect to the mini-blind products.
[0083] After the first ends of the pleated head rail and bottom
rail are sized, the pleated material is slid into openings channels
132, 134 of the stationary die 104 and openings 164, 166 of the
movable die 106. The dimension of the guide die plate 108 proximate
opening 140 does not permit the head rail and bottom rails to pass
into opening 140 and is stopped a predetermined distance from the
cutting plane. In the preferred embodiment, the distance from the
ends is one inch. The end locator is used to size the pleated
material. The end locator set block 100 received between the
pleated shade bottom rail and head rail such that the set block 100
pushes the pleated material forward the sized end of the bottom
rail and head rail a predetermined distance. In the preferred
embodiments the set block extends one inch from the first side of
the end locator extension to compensate for the one inch distance
the bottom rail and head rails are short of the cutting plane 88.
In this manner when the pleated material is sized by blade 174 the
width of the pleated material is the same as the width of the head
rail and bottom rail.
[0084] The process is repeated on the second ends of the pleated
shade head rail, bottom rail and pleated material. Where the head
rail and bottom rail are not symmetric the second ends of the head
rail and bottom rail will not fit in channels 132, 134. The second
ends of the head rail and bottom rail must be inserted into
channels 136, 138 respectively, that are configured to accommodate
the different orientation of the second ends of the pleated shade
bottom rail and head rail.
[0085] Alternatively, the stock pleated shade product may be sized
in three steps. First the head rail and bottom rail may be sized by
cutting material off from a single end to the final width of the
customer's specification. Since the head rail and bottom rail are
being sized from one end only, a full scale may be utilized to
locate the head rail and bottom rail relative to the cutting plane.
The pleated material is then cut equally on both sides in two
separate cutting operations so that the lift cords remain symmetric
about the center of the head rail and bottom rail.
[0086] Referring to FIGS. 25 and 26, the sizing of the cellular
product in two steps is illustrated. In the first step the entire
portion to be removed from the stock cellular head rail and bottom
rail is removed in a single operation of the movable die 106 (FIG.
8). Accordingly, the cellular shade may be located relative to a
cellular scale 202 having full scale indicia such that the markings
on the scale 202 (FIG. 4) reflects the actual distance from the
cutting plane 88. The end locator 52 is utilized to locate the
cellular product to be sized. The head rail and bottom rail of the
cellular product are inserted into channels 132, 134 (FIG. 8) while
the other ends of the head rail and bottom rail that are not to be
sized are located against the first side of the end locator 52. The
first side of the end locator 52 is aligned with the full scale
indicia of scale 202 corresponding to the actual width of the blind
as requested by the customer. When the head rail and bottom rail
are being sized the cellular material is slid away from the ends of
the blind to be cut off and towards the second cutting station 18.
The cellular material is allowed to pass through end locator 52
extension 94 via opening 102.
[0087] Once the head rail and bottom rail have been cut to size,
the cellular material is slid past the newly cut ends of the head
rail and bottom rail into openings 140 and 172 of the stationary
and movable dies 104, 106 (FIGS. 8, 9) respectively. The end
locator set block 100 pushes the cellular material the required
distance into the first cutting station to ensure that the cellular
material will have the same width as the head rail and bottom rail
once it is sized. The set block 100 is utilized the same way for
the cellular material as for the pleated material discussed
above.
[0088] Referring to FIGS. 12-16 the second cutting station 18
includes a vertical head rail shearing mechanism 204 and a wooden
blind sizing mechanism 206. Vertical shearing mechanism 204
includes a stationary die 208 having a channel 210 for receiving a
head rail of a vertical blind product. The stationary die 208
includes a second opening 211 for receiving the traverse rod of the
vertical blind product. A movable die 212 moves relative to the
stationary die 208 in a vertical up/down direction. Movable die 212
includes a shearing portion 214. Additionally, vertical shearing
mechanism 204 includes a punch 216 that punches a hole in the base
of the vertical blind head rail a set distance from the cut end of
the head rail as described below. A vertically oriented piston 217
moves the movable die 212 upward and downward as illustrated in
FIGS. 13 and 14 respectively.
[0089] Turning to FIGS. 12, 15 and 16, the wooden blind sizing
mechanism 206 includes a circular saw 218 having a circular blade
220 that moves from a first position proximate the rear wall 34 to
an extended position in the cross housing direction toward the
front wall 28.
[0090] The sizing of a wooden blind having a metal head rail, a
wooden bottom rail and wooden slats will now be described. While a
pin locator 48 could be used to locate the wooden blind for sizing,
the center clip locator 50 will be described in connection with the
sizing of the wooden blind. As illustrated in FIGS. 22 and 23, a
head rail includes an opening 86 that receives a protrusion or tab
extending from clip 80. In this manner the clip is positively
located on the center of the head rail 82. The clip 80 is then
positioned within slot 78 of the center clip locator 50, which
positions the clip and the head rail relative to the second half
scale 76. A pointer 74 on the center clip locator identifies the
center position of the wooden blind to be sized relative to the
cutting plane 92 of the circular saw 218.
[0091] Once the head rail and clip are located within the slot of
the center clip locator, the wooden blind bottom rail, slats and
head rail are slid into a first opening 221 in the second cutting
station (See FIG. 28). The wooden blind is located by moving the
center clip locator 50 to align the pointer 74 of the center slat
locator with the customer's width specification on the second scale
76.
[0092] Once the wooden mini-blind is at the proper location to be
sized, the end locator 52 is used to square the ends of the head
rail, slats and bottom rail, by using the second side extension
second side 98. A clamp mechanism 222 clamps the bottom rail, the
wooden slats and the head rail against a stop 224 (See FIG. 29)
such that the sides of the rails and slats are parallel to the top
working surface 36. This removes any space distance between the
slats, the bottom rail and the head rail.
[0093] Once the bottom rail, slats and head rail have been located
within the opening 221 and clamped against the stop 224, the first
end of the wooden mini-blind is ready to be sized. As with the
first cutting station 16, the operator first enters the access code
in the center access panel 22 to allow activation of the second
cutting station 18. To activate the sequence for sizing the wooden
blind bottom rail, slats and metal head rail, the operator turns on
the second cutting station 18 with the on/off switch. By
simultaneously depressing two activation buttons, the following
sequence is activated. First the vacuum 46 is started and the
circular saw 218 is activated and moved toward the front wall 28
along cutting plane 92 cutting the bottom rail, slats and head rail
until the bottom rail, all of the slats, and the head rail are each
sized. The circular saw 218 is then moved rearward until it is in
its fully withdrawn position. In the preferred embodiment the
movement of the saw is automated and controlled by the controller
22.
[0094] In addition to wooden slats, the circular saw 218 may also
size faux wood slats made of a cellulose plastic formulation or of
slats made from a plastic material, or any other type of material
that can effectively be sized with a circular saw. The circular saw
218 includes a circular saw blade 220 that travels along a cutting
path 92.
[0095] It is also possible to size a valance for the wooden blind
at the same time the head rail, bottom rail and slats are being
sized. The valance is simply located adjacent the head rail or
bottom rail and sized along with the other components.
[0096] A vertical blind may also be sized in the second cutting
station 18. A vertical blind head rail is sized in the vertical
shearing mechanism 204 by locating the vertical blind head rail in
the vertical blind head rail channel 210. The vertical blind
traverse rod is located within the traverse rod opening 211. Since
the vertical blind does not include lift cords, the vertical blind
head rail may be sized by removing material from a single side of
the stock head rail. Accordingly, a scale 225 (FIG. 4) having full
scale indicia are used to determine the width of the vertical
blind. Again, the width of the vertical blind is measured to
correspond to the width of the window it will be covering. The
cutting plane of the vertical shearing mechanism 204 is not in the
same plane as the cutting plane 92 of the circular saw. The
vertical shearing mechanism is set inward in the housing to permit
the circular saw to fully extend along its cutting plane 92 without
contacting the shearing mechanism. The scale 225 measures the
actual distance to the cutting plane of the vertical shearing
mechanism 204.
[0097] The vertical shearing mechanism 204 also includes a punch
216 to place an aperture in the base of the vertical head rail a
set distance from the cutting plane of the vertical shearing
mechanism 204. The aperture is located a predetermined distance
from the cut end of the head rail to receive a portion of a snap-in
end cap to be added to the vertical head rail once it has been
sized. The aperture could also be used to receive a fastener such
as a screw to secure an end cap to the head rail. Punch 216 is
pivotally connected to a lever 228 that is pivotally connected to
the vertical shearing mechanism 204. The lever 228 is pivotally
connected to a head portion 230 of a rod 232 which is slidably
located in a holder 234 attached to the movable die 212. The head
portion 230 includes a base portion having a diameter larger than
the rod 232 and larger than the opening in the holder 234.
[0098] The operation of the vertical shearing mechanism 204 for
sizing the vertical blind head rail will now be described. Since
the vertical blind head rail can be sized by removing material on
one side of the head rail, no centering locating mechanism need be
used. Rather, the vertical blind head rail can be measured by use
of the full scale indicia on scale 225. The end of the vertical
blind head rail to be cut is placed in channel 210 and the traverse
rod is placed in opening 211. The free end of the head rail that is
not being sized is aligned with the full scale indicia indicating
the customer's specification for the desired width of the vertical
blind product. The vertical slats will be sized to a different
measurement, since the important feature of the vertical slats is
their vertical length when they are placed over a window. Once the
vertical blind head rail and traverse rod are located in the
stationary die 208 the operator activates the shearing mechanism by
following the steps outlined above of inputting the access code,
turning the on/off switch to the on position for the second machine
cutter, and depressing the two activation buttons.
[0099] The movable die 212 will move in an upward direction until
the "v" shaped shearing portion 214 contacts and shears the
vertical head rail and the traverse rod. Once the holder contacts
the base of the head portion 230, the head portion is moved upward,
thereby causing the pivot of lever 228 about its pivot point and
causing the punch 216 to extend downwards through the head rail. In
this manner, an opening is formed in the vertical head rail a
predetermined distance from the sheared end of the vertical head
rail.
[0100] Once the movable die has reached its fully extended upward
position and the head rail and traverse rod have been sheared and
the opening has been punched in the head rail, the movable die is
retracted downward to the starting position. The vertical blind
slats may also be sized in the second cutting station 18 to a
customer's specifications. The vertical slats extend in a vertical
position and therefore are likely to have a dimension different
than the head rail width. The vertical slats are clamped down onto
top working surface 36 with a vertical clamp 236 (See FIG. 30) such
that the face of the vertical slats are parallel to the top working
surface 36. If the vertical blind head rail is longer than the
space between the first and second cutting stations 16, 18, the
first cutting station 16 may be lowered to a third position as
discussed above to allow the vertical head rail to rest
horizontally on the top working surface 36. When the first cutting
station 16 is lowered to the third position, the top of the frame
178 is substantially flush with or lower than the top working
surface. The scale extension 180 is located in housing 20 and
extends the full scale 226 (FIG. 4) that measures the actual
distance to the cutting plane 92.
[0101] Unlike the wooden mini-blind product in which the bottom
rail, slats and head rail are all positioned relative to the second
cutting station together, the vertical head rail and vertical slats
are positioned and sized separately.
[0102] In another embodiment, each scale is used for sizing a
specific blind or shade product. Further, each scale may have a
separate distinct color that corresponds with the color of the
packaging for respective blind or shade product to be sized. As a
result, an operator will be able to determine which scale to use to
size the stock blind or shade product by matching the color of the
stock blind or shade packaging with the appropriate scale. The
instructions that are located on the housing may also be in color
to further reduce the chance that the particular stock blind or
shade product is sized incorrectly. Additionally, the instructions
that are located in an instruction manual may also be color
coordinated with the scale and stock product packaging. Since the
scale, packaging for the blind or shade product and instructions
all share the same color for sizing of a specific product, the
chance of error decreases, resulting in an easier process for the
operator.
[0103] In a further embodiment, the locator pin may be eliminated.
The blind or shade product may include a mark or feature that is
located on its longitudinal center. This mark or feature would be
aligned with the appropriate marking on the appropriate scale as
discussed above. While the locator devices provide for a positive
placement of the blind or shade product, it is possible to locate
the center of the blind or shade product by means of a mark such as
a line placed on the product in the factory before being shipped to
the retain outlet. Of course the mark could also be placed by the
operator in the retail outlet as well prior to sizing.
[0104] The stock blind or shade product would also have a feature
such as an indentation, groove or protrusion on the center of the
blind that could be used to locate the stock blind or shade product
relative to the scale.
[0105] While the detailed drawings, specific examples and
particular formulations given describe exemplary embodiments, they
serve the purpose of illustration only. The systems shown and
described are not limited to the precise details and conditions
disclosed. Furthermore, other substitutions, modifications,
changes, and omissions may be made in the design, operating
conditions, and arrangement of the exemplary embodiments without
departing from the scope of the invention as expressed in the
appended claims.
